I'm planning to pour a cement footing that's 30 inches by 30 inches wide and 20 inches deep, intended to support a steel beam that will be positioned right in the center. I've watched various videos about rebar installation for flat concrete pads, but I'm unsure how to approach rebar for something that's more vertical like my footing. Additionally, how should I arrange the rebar around the beam? Any tips would be appreciated!

Honestly, if you're unsure about these basics, it might be best to reconsider DIY-ing this project. It could lead to serious issues down the line.
The rebar requirements really depend on the load the footing will bear and the soil conditions. It’s not just a straightforward guess. For instance, the base of construction tower cranes often involves a significant amount of steel—sometimes up to 25%! Make sure you're informed about what your specific project needs before starting.
Clarifying what you mean by the beam is vital. If it’s actually a post that’s going into the concrete, you need to ensure it’s embedded correctly. If it’s just resting on top with brackets or bolts, that changes things. If it's in the concrete and might face lateral movement, you'll want to bend the rebar at the corners to reinforce it. Consult with your local steel supplier for specific materials and recommendations!
You can find a ton of helpful videos on YouTube. I just searched for "rebar to beam footing connection" and loads popped up! They explain how to handle rebar in situations like yours, so definitely give that a try.
I get that, but everyone starts somewhere, right? Isn’t it okay to ask questions as a beginner? I thought this community was for sharing knowledge.
